problem with gadu-gadu

Hey, I've got a problem with Polish messenger called "Gadu Gadu". I've been using the 2.10.0 version of pidgin on Windows and I didn't have any problems until one day when suddenly I've been loged out with a communicate "Nie można odczytać z gniazda". I've installed the newest version but the problem still exists. I can still log in by the gadu-gadu software. What can cause that problem? How cane I solve it and still enjoy using pidgin? ;)
Greets!
